What type of computing involves one or more computers connecting to a central computer for resource sharing?

The concept described involves a centralized model where one or more computers, often referred to as clients, connect to a central server to access resources, services, or data. This is characteristic of client-server computing. In this architecture, the server provides resources or services such as storage, applications, or processing power, while the clients are devices that request and utilize these resources.

Client-server models are prevalent in various applications, such as web services, database management, and resources sharing in networks. This setup allows for centralized control, easier management of resources, and streamlined updates or maintenance since changes need to be made only on the server rather than across all individual client machines.

In contrast, other models such as peer-to-peer computing do not rely on a central server, as each device acts both as a client and a server, sharing resources directly with one another. Cloud computing, while it may involve a similar client-server relationship, usually emphasizes on-demand resources provided over the internet rather than a direct connection to a central computer in a more traditional sense. Virtual computing involves creating virtual instances and environments, which also doesn't align with the description given.

Recognizing these distinctions helps clarify why the client-server model is the most accurate answer in this context.
